stickingmaterial, usually prepared paper,

and thetclosing material, usually cork.

The special object is to assemble the tin, paper and cork permanently in one machine, rapidly, securely and efficiently. Y

Brieiiy the' invention contemplates feed- Y ing and heating the tins, inserting the paper,

either before, during or after heating, but preferably before heating, driving a cork into a tin by a hard blow, squeezing the parts together to insure complete sticking and then ejecting the finishedcap.`

lln the form of mechanism illustrated the tins are fed from a rapidly rotated dial onto a transfer belt which delivers them successively to va feeding slide. The paper is placed in the tins in any convenient manner. The slide is heated so as to heat the tins as they are fed along the slide. The heated tins soften the prepared paper. The corks are fed intermittently into position above the tins'and driven downward against the tacky paper into the tins by spring pressed plungers, the parts thus assembled are stuck at the same" time. The sticking or sealing papers may be placed in the tins by hand or automatically in any suitable manner at any time priorto the time that the tins are fed under the corks, but preferably before heating the tins. After the plunger' drives a cork by spring, pressure into a tin, a. mechanie'al pressure by means of a lever is applied to the plunger to squeeze the cork in the tin. A number of plunger-s are carried by a Y turretwhich rotates intermittently so that a.

tin is fed and a cork assembled and stuck at each stroke of the successively rotating turret plungers. As the turret rotates the plungers are successively lifted by a cam and the completed caps directed from the turret to a belt which carries them to a suitable inspecting table.

Figure 1, is a plan view of the principal q I parts of a machine embodying the improvements of my invention, Fig. 2, is a vertical I longitudinal section of the same through the feeding and heating slide.` Fig. 3 is a front view of the squeezing device and showing the plunger lifting cam. Figqf, isa crossV sectional view of the tin feeding and heating chute.

The tins or shells are inspected on a suitable table (not shown) and fed onto a suitable rotating dial 5. From this they are directed by a flange 6 on to 'a belt Y, operated by suitable means and which delivers them on to the reciprocating feeding slide 8. rlhe arm 9 which is secured to the outer end of the feeding slide 8 has a roller 10I pressed against the camV 11 for instance by a spring 12. Thecam 11 is on themain drive Vshaft 12 so that as this shaft rotates, the

arm 9 and the slide 8 are reciprocated. YThe slide 8 has a shoulder 13 for engaging the Successive tins to feed them forwardly. A pair ofspring pressed plungers 14, 14 serve to prevent the tins from moving backward with the slide on which they rest. As the slide is moved forward the spring pressed plungersl are interposed behind the end tin and thus hold and prevent it going back with the slide. As the slide moves back, the end tin is thus held and drops onto the support 1 6 in front of the rotating turret.v This turret has a moving table member 1'( adapted to receive the tins which are fed forwardly intermittently lfron'r the support '1G as the slide moves forward.

The corks are supplied in a chute 20 and fed forwardly Aintermittently from the bottom by a feedingslide 21. This slide 21 is operated by an arm 22 pivoted at 23 and which has a roller 24 operated in a groove of the cam 25. `This `cam is on the shaft 12 and swings the arm 22 backward and for ward once at each rotation of the shaft. The cork feeding slid@ and the tin feeding slide are thus operated syncl'nonously. Each cork is fed into the top of the tapering pas sage 26 immediately above the tins. A 'paper disk havinga sticking composition has been inserted in each tin at a onvenient time prior to insertion of the cork.

The tins are heated in the feeding chute on the slide 8 in any convenient manner for instance, by means of a burner 28. rlhe bottom of the slide may have a' series of.opcn

, ings such as 29 for the heat to more directly ffii lie

pass through to the tins. The chute may also have lateral anges 30, 30 to conne the heat. The temperature may be regulated as required by the particular necessities of the materials employed and the speed of operation. The-hot tin softens the prepared paper so that it is ready to stick the cork the instant the cork is inserted.

The turretl is rotated on the shaft32 intermittently by the action of a pawl 33 connected to the arm 3ft-ei thecam :operated lever pivoted at '23, so that the' turret is rotated' step by step at each feeding stroke of the* tinsl and-ycorks.' The turret carries a series of plu'ngers 35 whichI are guided in a plate 36 atthe' top and in a plate 37 near the bottom just above the plate 38 which has the tapering cork passages 26. The lower end of each Aplunger is suitably shaped to.

apply a pressure on the cork in the proper manner. Each plunger is pressed downward by a spring'39 which is'housed within the upper end of the plunger and the plate 36.

Each plunger carries a roller 40 on a shaft 41 ing in a notch 44 in the cam 43. The turret is stopped in proper position by the yielding stop l5' which intercepts the roller 40.

As the cork is inserted in the turret, the stop is raised and as the turret is rotated clockwise, the roller 40 drops off to the left from the tip of the cam 43 and striking the cork beneath itdrivesfit into the tin on the table 17, striking a sharp blow. The tapered guide 26 contracts the edge of the cork so that it is uniformly fed into the tin. The lever 46, pivoted at 47, is connected by-a pin and slot engagement 48 to a projection 49 from the arm 22 so that as the arm oscillates, the lever 46 is rocked. The lever 46 carries the yielding stop 45, previously referred to, and also has a cam face 50 below its right hand end. The arrangement and proportions of the parts are such that when the roller 40 drops down from the tip of the cam 43, the lever 46 is tilted and rocks its right hand end and cam 50 down onto the roller 40 so as to force the roller and plunger 39 downward and positively squeezethe cork into the tin. This distributes thV sealing and sticking material so that the parts are uniformly united.

As the turret rotates, the rollers and their plungers are successively lifted by the right hand and. 52 of the cam 43. This releases the finished caps which 'are directed outwardly from the turret by the finger 54. They thereupon fall through the opening onto a suitably operated belt 56 which conveys them out onto an inspecting table, not shown.

By this machine the assembling'of the caps is done rapidly and the parts are securely united.
